The Backstreet Boys' Surprise Performance Adds Extra Excitement For Their Upcoming Vegas Residency — VIDEO

If you grew up in the '90s and early '00s, please have a seat. This news may be too much to handle while standing up. The Backstreet Boys announced that they're reuniting and doing a Las Vegas residency. And in case you needed some extra incentive to see their show, Backstreet Boys gave a surprise performance at the iHeartRadio Music Festival and it was the perfect dose of nostalgia. According to E! News, they were joined on stage by Florida Georgia Line. They reportedly performed "Everybody," "I Want It That Way," and "As Long As You Love Me." Basically, they covered all the classics.

It's been 23 years since the band first formed in 1993. But don't worry, they've still got it. And by "it," I mean the voices and dance moves to perform those same songs you've loved since middle school. I'm not saying that they're the greatest boy band there ever was (obviously that would be *NSYNC), but they definitely hold a special place in pop culture history.

This little preview from the iHeartRadio Music Festival is an awesome advertisement for their upcoming Vegas show, because it gives just a taste of the music they'll be performing. The Las Vegas residency will start on March 1, 2017. Tickets for the 18 performances go on sale on Oct. 1, so you may want to prepare yourself accordingly.

Don't you feel like you just hopped in a time machine back to 1997? So good.

And here's a photo they shared thanking Florida Georgia Line, showing they enjoyed the performance just as much as their fans.

This makes it official. As their lyrics say, "Backstreet's back. Alright!"
